Vane pump working principle and advantages and disadvantages
Vane pump in the life of a wide range of applications, but do you know the vane pump principle? Xiaobian now to tell you the vane pump principle and vane pump advantages and disadvantages! Vane pump vane pump working principle Vane mounted in the slotted rotor, the rotor eccentric installed in the pump body, the rotor rotates, the vane slides out of the rotor, close to the surface of the pump slide, rotor, slide The cavity formed by the pump and the rotor rotates with the rotation of the rotor, and the space size changes cyclically. When the cavity increases, the medium is drawn in. When the cavity becomes smaller, the medium is discharged and circulated to complete the medium transportation process. Second, the advantages of vane pump YPB series self-priming vane pump, the rotor with a vane driven liquid. Material ductile iron with self-lubricating blades. Because of its excellent performance, it can transport viscous and volatile liquids, compared to the same pump power lower. In the low-speed large-flow transmission more advantages. Fast, low noise long-term use; leaf structure to make it stable, trouble-free use. And self-absorption ability, long life, small size, high efficiency. In the case of conveying gasoline, diesel or similar medium, the vane pump has a very big advantage, is a self-priming centrifugal pump and copper gear pump replacement. Third, the shortcomings of vane pump (1) self-priming pump gear performance worse than the more stringent requirements of the suction conditions, the speed range must be 500 ~ 1500r / min range. (2) is more sensitive to oil pollution, leaves easily killed by impurities in the oil, poor work reliability. (3) the structure is more complex, higher precision parts manufacturing, higher prices.
